人教必修一Unit 4 定语从句之关系代词(解析版)
第09练定语从句之关系代词定语从句的先行词和关系词在复合句中作定语，修饰主句或主句中某一名词或代词的从句叫定语从句。
定语从句由关系词引导。
限制性定语从句表现为在意义上是先行词不可缺少的定语，若省略，主句的内容就不完整或失去意义；它和主句的关系十分密切，不可用逗号分开。
先行词是被定语从句修饰的名词或代词。
关系词指代先行词，在从句中作一定的句子成分。
引导定语从句的关系代词有which，that，who，whom，whose，as等。
先行词是定语从句修饰和限定的成分，从构成上而言，它可以是名词、代词、名词性短语等；从句子成分上而言，它可以是主句的主语、宾语、表语等。
下面，我们从两个实例来看一下定语从句及其相关成分的分布：1.关系代词that即指人又指物；作主语或宾语（作宾语时可省略）只用于限制性定语从句中，介词后面不能跟that。
当代替物时，可以与which通用。
Yesterday Emily was wearing the new dress that I gave her．昨天艾米丽穿了我送给她的新衣服。
I have a friend that likes listening to classical music我有个朋友喜欢听古典音乐。
2.关系代词which指物；作主语或宾语（作宾语时可省略）在非限定性定语从句中，只宜用which,不能用that.在限定性定语从句中，可用在介词之后。
My parents live in a house which is more than 100 years old我的父母住在一座具有100多年历史的房子里who,whom指人；作主语或宾语（whom常可省略）先行词必须为人。
Who可代替在从句中担任宾语的whom,若前有介词，须用whomA couch potato is a person who spends a lot of time watching TV．“A couch potato”指那种成天沉湎于电视中的人。

三、知识精讲
一、定语从句 定语从句：修饰名词或代词的从句，一般紧跟在
所修饰的先行词后，有限制性定语从句和非限制 性定语从句两种。定语从句由关系代词或关系副 词引导，相当于一个（长）形容词，所以又称为 形容词性从句。
关系词常有三个作用：引导定语从句，指代先行词， 在定语从句中担当一个成分（主语、宾语、定语）。
Unit4 单元语法 定语从句讲解素材 人教版高一英语必修第一册
新人教高一英语必修一U4 Natural Disasters 语法定语从句一．定义：定语是用来修饰名词或代词的，起限定作用的成分。
定语可以由形容词、名词、代词、数词、分词（现在分词或过去分词）、不定式（短语）、介词短语等来充当，也可以由一个句子来充当。
充当定语功能的句子就是定语从句。
二、定语从句三要素1. 先行词：被修饰的名词/代词/整个主句2. 关系代词：连接先行词与定语从句（that, which, who, whom,whose）3. 关系副词：连接先行词与定语从句（where, when, why）注意：关系代词/副词的选择→看定从是否完整句子完整→用关系副词缺少成分→用关系代词定从=先行词+关系词+从句例：I know the girl. The girl is in red. (两个简单句)→I know the girl who is in red. （定语从句）例句中被修饰的词是the girl, 这个词就称为先行词。
其中连接两个句子的是who，称为关系词。
关系词在从句中指代先行词，并在从句中充当一定的成分，观察上句，关系词在从句中充当主语。
☆总结：关系词有三个作用：（1）连接定语从句; （2）、指代先行词；（3）、在从句中充当成分关系词的用法如下表：三、关系代词的用法：定语从句中缺少主语、宾语、表语、定语用关系代词。
在从句中作宾语时，关系代词常可以省略。
1.that的用法that指人或物，在定语从句中可作主语、宾语或表语，但that不用于引导非限制性定语从句。
例：The letter that I received was from my father.The girl that has long hair is my sister.The city is no longer the one that it used to be.注意：用that不用which的情况2.which 的用法which指物，在从句中作主语或宾语。
外研版新版必修一UnitFour(Friendsforever)语法讲解
1essonFour1定语从句的定义与分类在复合句中，修饰某一名词或代词的从句叫定语从句。
被修饰的名词或代词叫先行词，定语从句一般放在先行词的后面。
根据定语从句与先行词的关系，定语从句可分为限制性定语从句和非限制性定语从句。
前者紧跟先行词，主句与从句不用逗号分开，从句不可省去；后者主句与从句之间用逗号分开，起补充说明作用，如果省去，意思仍然完整。
2.关系代词的用法(I)WhO的用法：WhO指人，在从句中可作主语、宾语和表语。
(2)whom的用法：WhOm指人，在从句中作宾语，此时也可用WhO代替。
(3)whose的用法：whose既可指人也可指物，在从句中修饰名词作定语，相当于所修饰成分的前置所有格。
它可以转化为“the+名词+ofWhiCh/whom"和"ofwhich/whom+the+名词”的形式。
(4)that和which的用法①WhiCh指物，that既可指人也可指物；它们在从句中作主语、宾语或表语，WhiCh 和that在从句中作宾语时可以省略。
②在限制性定语从句中，关系代词指物时只能用that而不用which的情况a.当先行词是a11,1itt1e,few,none,anything,something,everything,nothing等词时。
b.当先行词是序数词或形容词最高级或被序数词或形容词最高级修饰时。
c.当先行词被theon1y,thevery,thesame,theright等修饰时。
d.当先行词既有人又有物时。
③句中其他位置已出现与关系代词相同的疑问词时，应避免重复。
难点分析一：(I)Whatif用于提出假设时，意思是“倘若……，假若……怎么办，要是……将会怎么样”，其后句子可用陈述语气(一般现在时)，也可用虚拟语气(一般过去时或ShOUk1+动词原形；若是针对过去情况，从句则用过去完成时)。
(2)Whatif表示邀请或建议时，意思是“……怎么样？如果……如何？”。
